   1 """SCons.Tool.rpmutils.py
   2
   3 RPM specific helper routines for general usage in the test framework
   4 and SCons core modules.
   5
   6 Since we check for the RPM package target name in several places,
   7 we have to know which machine/system name RPM will use for the current
   8 hardware setup. The following dictionaries and functions try to
   9 mimic the exact naming rules of the RPM source code.
  10 They were directly derived from the file "rpmrc.in" of the version
  11 rpm-4.9.1.3. For updating to a more recent version of RPM, this Python
  12 script can be used standalone. The usage() function below shows the
  13 exact syntax.
